Thermal Overload Relay Setting = 70%X12.28 = 8.6A Max.

The overloads are determined using 125% of the fla, 7a x 1.25 = 8.75a. (a) 40a (c) 60a (b) 50a (d) 70a. The motor fla calculator uses the following formulas:

Thermal Overload Relay Setting = 120%X12.28 = 14.7A

Protection against phase failure (single phasing) / voltage unbalance. There is one cylindrical stator and a three phase winding is symmetrically distributed in the inner periphery of the stator. An example calculation to size a motor overload protection device is:

The Overload Relay Is Wired In Series With The Motor, So The Current That Flows To The Motor When The Motor Is Operating Also Flows Through The Overload Relay.
